Subject: [PATCH v3 2/7] drivers: regulator: qcom_spmi: Refactor get_mode/set_mode
Date: Thu, 13 Jun 2019 07:22:39 -0700 [thread overview]
Message-ID: <20190613142239.8779-1-jeffrey.l.hugo@gmail.com> (raw)
In-Reply-To: <20190613142157.8674-1-jeffrey.l.hugo@gmail.com>
spmi_regulator_common_get_mode and spmi_regulator_common_set_mode use
multi-level ifs which mirror a switch statement. Refactor to use a switch
statement to make the code flow more clear.
